Onni is a toolbox created for online experiments. You can think it as a
merger of super simple E-prime or Presentation and hassle-free Webropol /
Google docs that can also handle bodily sensation mapping (emBODY
measurements). It is geared towards getting fast ratings for video /
audio / image / text stimuli and setting up simple questionnaires, but
is easy to customise towards other uses too. Setting up experiments is
really fast. Web-based user interface with simple formatting options and
batch stimulus upload & questionnaire generation allows deploying
studies in minutes. Data are stored centrally and accessible. Onni is a
Flask app using MariaDB.
